Overview

EN 1850-2:2001 - Flexible sheets for waterproofing - Determination of visible defects - Part 2: Plastic and rubber sheets for roof waterproofing (CEN) defines a simple, visual inspection method to detect surface and internal visible defects in thermoplastic and elastomeric roof waterproofing sheets. The standard targets defects that could influence the functional behaviour of plastic and rubber sheets used for roof waterproofing, helping manufacturers, test laboratories and specifiers ensure product quality before installation.

Key topics and requirements

  • Scope: Applies to plastic and rubber (thermoplastic and elastomeric) sheets for roof waterproofing; assesses defects that may affect performance.
  • Definitions: Clear terms for defects such as blister, crack, hole, scratch, indentation, void and inclusion.
  • Sampling: Rolls selected and sampled in accordance with EN 13416 (rules for sampling).
  • Conditioning: Examination normally at ambient conditions. In case of dispute, condition samples at (23 ± 2) °C for at least 20 hours and test at (23 ± 2) °C.
  • Inspection procedure:
    • Unroll the first 10 m of the selected roll on a flat surface, top surface uppermost; visually examine both surfaces for blisters, cracks, holes, scratches, indentations and other visible defects.
    • Turn the roll and inspect the underside.
    • Cut the roll near the end across its full width and examine the cut surface for voids and inclusions.
  • Test report requirements: Must reference EN 1850-2, identify the tested product, note any deviations or non-standard procedures, record presence and type of defects (blisters, cracks, holes, inclusions, voids), and the date of testing.

Applications and users

  • Manufacturers: Incoming/outgoing quality control to detect defects that can affect waterproofing performance.
  • Third‑party test laboratories: Routine checks or dispute resolution using the defined conditioning and reporting rules.
  • Specifiers and procurement teams: Acceptance criteria for delivered rolls when writing product specifications or purchase contracts.
  • Roofing contractors and consultants: Visual pre-installation checks to reduce on‑site failures.
  • Certification bodies and standards committees verifying conformity to European product requirements.
